Thanks for asking Michael, The trans gearing appears to be a very good match. The engine actually feels very similar to the Suby engine in my Speedster but I think it is going to have more power once I explore 1/2 throttle to full open driving, I haven't pushed the engine yet. The funny thing is that I am running the exact same A-1 muffler on both cars as well. I had little doubt the trans would be a good match. I really like the gear ratio choices they build this trans with. All the gears are a tad taller and 4th gear gives me 70 MPH at 3200 rpm. So yes to me it feels like a good match.
